Summary
The sensitivity of the LOFT plant to different main steamflow control valve closure and opening times is examined using a hybrid computer simulation. Results for seven valve opening rates and seven valve closing rates are presented and discussed. Comparisons are made between this analysis and the current FSAR which assumes a 20 second full stroke motion rate. While full-stroke valve motion times of 1 to 40 seconds are shown to be acceptable with respect to safety margins, a motion time of 10 to 30 seconds is recommended to allow for adequate control sensitivity.
